revset: refactor parents() into a single return point Both paths are doing similar thing in the end. We refactor the function so that the `ps` set is commonly used at the end. This will end excluding `nullrev` from this set in a future patch

revset: remove nullrev from set computed in p1() and p2() The old code relied on the subset contents to get rid of invalid values. We would like to be able to rely more on the computation in p1() and p2() so we filter out the invalid value

revset: document the choice made in __generatorset.__iter__ The method code looks a bit ugly but has good reasons to. We document them to prevent naive refactoring in the future.

help: mention mode in hg log --removed help (issue4381)

commit: catch changed exec bit on files from p1 (issue4382)

revert: add a `drop` action This prevents the need for a try except in the `_performrevert` code.

revert: explicitly track added but deleted file Added + deleted file are files that need to be untracked from the dirstate but that are already missing on disk. The current `_performrevert` code is handling that with exception catching. We will be able to do better with a dedicated set.

revert: have an explicit action for "forget" The distinction between "remove" and "forget" used to be in special logic checking for the state of the file in the dirstate. Now that we have dedicated filtering, we can stop relying on this logic and have two distinct actions.

revert: split between newly added file and file added in other changeset These two kinds of files are handled differently. One is deleted and the other is just forgotten (the file is untracked but left in place). The distinction is done in the `_performrevert` code itself and we would like to get ride of this.

revset: stop using a baseset instead of a plain list in _revsbetween The function internal code needs a list. Lets use a list.

run-tests: added 'cuser', 'csys' time info in report.json file This patch adds up a 'cuser' and 'csys'(cputime) info in report.json file which generated when --json is enabled while testing. Now the new format of report.json file is as below. testreport ={ "test-success.t": { "csys": "1.041", "cuser": "1.041", "result": "success", "time": "2.041" } "test-failure.t": { "csys": "1.041", "cuser": "1.041", "result": "failure", "time": "4.430" } "test-skip.t": { "csys": "1.041", "cuser": "1.041", "result": "skip", "time": "3.754" } }

import: let --exact 'work' with --no-commit (issue4376)

obsolete: use C code for headrevs calculation Previously, if there were filtered revs the repository could not use the C fast path for computing the head revs in the changelog. This slowed down many operations in large repositories. This adds the ability to filter revs to the C fast path. This speeds up histedit on repositories with filtered revs by 30% (13s to 9s). This could be improved further by sorting the filtered revs and walking the sorted list while we walk the changelog, but even this initial version that just calls __contains__ is still massively faster. The new C api is compatible for both new and old python clients, and the new python client can call both new and old C apis.

revset: simplify orderedlazyset creation in spanset method We can simply use the `self.isascending` value instead of more complex if/else clause. This get the code simpler. Benchmarks show no performances harmed in the process.

revset: use spanset.isdescending in multiple simple places We call the method directly instead of duplicating checks. Benchmarks show no performances harmed in the process.

revset: wider definition of ascending and descending for spanset Before this patches, empty spanset were seen as neither ascending nor descending. This is mathematically wrong and create some edges case. We put `isascending` and `isdescending` back on track so we can use them to simplify some of the spanset code. Benchmarks show no performances harmed in the process.

annotate: port to generic templater enabled by hidden -T option If the selected formatter is other than plainformatter, raw data are passed to the formatter. In this case, it isn't necessary (and not possible) to calculate column widths. Field names are substituted to be the same as "log" command. There are a few limitations: - "binary file" message is not included in formatted output. - no data structure for multiple files. all lines are packed to single list.

annotate: split functions to get data without applying text formatting This prepares for porting to generic templater API, where raw data should be passed to the formatter. makefunc() is necessary to build closure in list comprehension.

annotate: remove unused variable in calculation of column widths

annotate: build format string separately from annotation data This prepares for porting to generic templater API. Note that we cannot use '%*s' to pad white spaces because it doesn't take into account character widths, as described in 4f5a6df2af92.

formatter: convert float value to json It will be used to encode ctx.date().

formatter: have jsonformatter accept tuple as value This is necessary for "annotate" to encode ctx.date() in the same manner as jsonchangeset printer. It doesn't support list object because keeping mutable object in _item could be a source of hidden bugs. Also, I can't think of the use case.

formatter: extract function that encode values to json string This is the stub for tuple support, which will be used to encode ctx.date() in the same manner as jsonchangeset printer.

contrib/synthrepo: pass options to ctx.diff as kwargs, not a dict

contrib/synthrepo: only generate 2 parents if model contains merges If `hg analyze` is run on a revision set which contains no merges, then `hg synthesize` will raise IndexError trying to select from p2distance, which will be empty.

convert: add support to find git copies from all files in the working copy I couldn't think of a better name for this option, so I stole the Git one in the hope that anyone converting a Git repo knows what it means.

convert: add support to detect git renames and copies Git is fairly unique among VCSes in that it doesn't record copies and renames, instead choosing to detect them on the fly. Since Mercurial expects copies and renames to be recorded, it can be valuable to preserve this history while converting a Git repository to Mercurial. This patch adds a new convert option, called 'convert.git.similarity', which determines how similar files must be to be treated as renames or copies.

convert: for git, factor out code to add entries to a separate function We're going to call this for multiple files in one iteration in upcoming patches.

convert: for git's getchanges, always split entry line into components We always need to know whether the entry is a rename or copy, so split it up unconditionally.

convert: for git's getchanges, use explicit index for iteration Upcoming patches will add support for copies and renames, for which we'll need to access multiple lines of the difftree output at once.

convert: add initial docs for git sources Upcoming patches will add config options for git sources. This patch adds a place to document them.

color: document that changeset phases have labels It's very useful to be able to colourise csets according to their phases. There was no indication anywhere in the docs that this is possible. We use e.g. `changeset.secret = ` instead of `changeset.secret ='none'`, because otherwise this is a BC: it would nullify the effects given to log.changeset label that usually surrounds the changeset.{phase} labels. Specifying the label without any effect instead of 'none' is a true no-op change and purely documentation.

color: change the debug output format Before, the format was label(labeled text) # single label [label1 label2](labeled text) # multiple Now, it's [labels|labeled text] ..which should make things a bit more clear.

color: enable debug option to show labels This is a debug option for showing labels. This can be helpful for knowing which labels are available for colouring or to see the output when defining your own templates. A couple of tests are included.

color: document that labels are used for colorizing text It is a deeply hidden secret that it's possible to colorise so many things with so many different labels. This is an attempt to document this. The text is a bit long, but it seems as short as can be while documenting everything. Perhaps it should be hidden under a --verbose option.

contrib: add OS X p4merge to mergetools.hgrc

patch: enable diff.tab markup for the color extension The following patch splits up changed lines along tabs (using re.findall), and gives them a "diff.tab" label. This can be used by the color extension for colorising tabs, like it does right now with trailing whitespace. I also provide corresponding tests.

dirstate: copyedit exception for no beginparentchange call

revsetbenchmarks: add an additional roots() benchmark The existing roots(x - y) revset only considered the most recent 100 revisions. This was a good start. But expanding it to the full history of the repository can dramatically increase execution time and thus constitutes a useful benchmark.

merge with stable

mq: examine "pushable" of already applied patch correctly Before this patch, "hg qselect" with --pop/--reapply may pop patches unexpectedly, even when all of patches applied before "qselect" are still pushable. Strictly speaking about the condition of this issue: - before "qselect" - there are N applied patches - the index of the guarded patch X in the series is less than N - after "qselect" - X is still guarded, and - all of applied patched are still pushable In the case above, "hg qselect" should keep current status, but it actually tries to pop patches because of X. The index in "the series" should be used to examine "pushable" of a patch by "mq.pushablek()", but the index in "applied patches" is used, and this may cause unexpected examination of guarded patch. To examine "pushable" of already applied patch correctly, this patch uses "mq.applied[i].name": "pushable" is the function introduced by the previous patch, and it returns "mq.pushable(mq.applied[i].name)[0]".

mq: pop correct patches when changing pushable-ness of already applied ones Before this patch, "hg qselect" with --pop/--reapply may pop incorrect patches, because the index in "applied patches" is used to pop patches by "mq.pop()", even though the index in "the series" should be used. For example, when the already applied patch becomes guarded and it follows the already guarded (= not yet applied) one, "hg qselect" is aborted, because it tries to pop to guarded one. This patch uses "mq.applied[i - 1].name" to pop to the patch, of which the index in the "applied ones" is "i - 1".

mq: use "mq.applied[i].name" instead of "mq.appliedname(i)" for safety Before this patch, "hg qselect --reapply" is aborted when "--verbose" is specified, because "mq.appliedname()" returns "INDEX PATCHNAME" instead of "PATCHNAME" in such case and "mq.push" can't accept the former as the name of patch. This patch uses "mq.applied[i].name" instead of "mq.appliedname(i)" as the name of the patch to be pushed for safety. Now, there is no code path using "mq.appliedname()", and it should be removed to prevent developers from using it in the wrong way like this issue.

mq: report correct numbers for changing "number of guarded, applied patches" Before this patch, "hg qselect" may report incorrect numbers for "number of guarded, applied patches has changed", because it examines "pushable" of patches by the index not in "the series" but in "applied patches", even though "mq.pushable()" expects the former. To report correct numbers for changing "number of guarded, applied patches", this patch uses the name of applied patch to examine pushable-ness of it. This patch also changes the result of existing "hg qselect" tests, because they doesn't change pushable-ness of already applied patches. This patch assumes that "hg qselect" focuses on changing pushable-ness only of already applied patches, because: - the report message uses not "previous" (in the series) but "applied" - the logic to pop patches for --pop/--reapply examines pushable-ness only of already applied ones (in fact, there are some incorrect code paths)

annotate: remove redundant check for empty list of annotation data It isn't necessary because zip(*pieces) returns [] if pieces are empty, and pieces are empty only if lines are empty.

revset: lower weight for _intlist function The histedit command uses a revset like: (_intlist('1234\x001235')) and merge() Previously the optimizer gave a weight of 1.5 to the _intlist side (1 for the function, 0.5 for the string) which caused it to process the merge() side first. This caused it to evaluate merge against every commit in the repo, which took 2.5 seconds on a large repo. I changed the weight of _intlist to 0, since it's a trivial calculation, which makes it process intlist first, which makes merge apply only to the revs in the list. Which makes the revset take 0.15 seconds now. Cutting off 2.4 seconds off our histedit performance. >From the revset benchmark: revset #25: (_intlist('20000\x0020001')) and merge() 0) obsolete feature not enabled but 54243 markers found! ! wall 0.036767 comb 0.040000 user 0.040000 sys 0.000000 (best of 100) 1) obsolete feature not enabled but 54243 markers found! ! wall 0.000198 comb 0.000000 user 0.000000 sys 0.000000 (best of 9084)

revset: make parents() O(number of parents) Strip executes a revset like this: max(parents(_intlist('1234\x001235')) - _intlist('1234\x001235')) Previously the parents() revset would do 'subset & parents' which iterates over each item in the subset and checks if it's in parents. subset is usually the entire repo (a spanset) so this takes a while. Reversing the parameters to be 'parents & subset' means the operation becomes O(number of parents) instead of O(size of repo). It also means the result gets evaluated immediately (since parents isn't a lazy set), but I think this is a win in most scenarios. This shaves 0.3 seconds off strip (amend/histedit/rebase/etc) for large repositories. revset #0: parents(20000) 0) obsolete feature not enabled but 54243 markers found! ! wall 0.006256 comb 0.010000 user 0.010000 sys 0.000000 (best of 289) 1) obsolete feature not enabled but 54243 markers found! ! wall 0.000391 comb 0.000000 user 0.000000 sys 0.000000 (best of 4323)

revset: make descendants() lazier Previously descendants() would force the provided subset to become a set. In the case of revsets like '(%ld::) - (%ld)' (as used by histedit) this would force the '- (%ld)' set to be evaluated, which produced a set containing every commit in the repo (except %ld). This takes 0.6s on large repos. This changes descendants to trust the subset to implement __contains__ efficiently, which improves the above revset to 0.16s. Shaving 0.4 seconds off of histedit. revset #27: (20000::) - (20000) 0) obsolete feature not enabled but 54243 markers found! ! wall 0.023640 comb 0.020000 user 0.020000 sys 0.000000 (best of 100) 1) obsolete feature not enabled but 54243 markers found! ! wall 0.019589 comb 0.020000 user 0.020000 sys 0.000000 (best of 100) This commit removes the final revset related perf hotspot from histedit. Combined with the previous two patches, they shave a little over 3 seconds off histedit on large repos.

check-code: look for misuse of __bool__

formatter: correct bool testing which should be __nonzero__ in Python 2

contrib/synthrepo: return None to delete files on commit, don't raise IOError The internal commit API was changed in 650b5b6e75ed to expect None from the filectx function when a file is to be deleted, not an IOError. This change keeps synthrepo up-to-date.

wix: contrib/sample.hgrc is no more

dockerrpm: create a yum/dnf repo from the generated rpms This gives "PPA" functionality where users easily can stay uptodate with latest nightly build.

docker: add CentOS 5 There is no official CentOS 5 docker template so we use one from saltstack.

docker: use stable tags for fedora and centos A moving target is rarely useful.

dockerrpm: prepare source outside docker and just run rpmbuild inside docker Simplifies the rpm build process. We will use platform specific rpmbuild directories and will not clean them and will drop the explicit copy to build directory.

dockerrpm: run docker build process as the current user, not as root Docker can be run by ordinary users if they are in the docker group. The build process would however be run as a root user, only protected by the sandboxing. That caused problems with the shared directory where rpmbuild would be picky about building from sources owned by less privileged users and producing files owned by root. Instead, add a build user with the right uid/gid to the image and run the docker process as that user.

dockerrpm: better handling of specification of docker name

dockerrpm: check that docker is running correctly before building

buildrpm: introduce --rpmdir instead of using hardcoded rpmbuild dir Used as rpm _topdir when preparing spec and source and building rpms.
